Fertility and Lifestyle: Essential Facts Quiz Quiz

Explore key facts about fertility and how lifestyle choices impact reproductive health. This quiz covers biology, habits, and common conditions affecting fertility in both men and women.

1. Female Fertility and Age

   At what age does female fertility usually start to decline noticeably?

   1. Around 30–32 years
   2. Around 24–26 years
   3. Around 18–20 years
   4. Around 45–47 years

   Explanation: Female fertility typically begins a noticeable decline around 30–32 years due to reduced quality and quantity of eggs. Earlier ages, like 18–20 and 24–26, are generally still within peak fertility years. Around 45–47 years, most women are nearing menopause and fertility is much lower.

2. Hormone Assessment in Ovarian Reserve

   Which hormone is commonly tested to assess ovarian reserve?

   1. Progesterone
   2. AMH (Anti-Müllerian Hormone)
   3. LH (Luteinizing Hormone)
   4. FSH (Follicle-Stimulating Hormone)

   Explanation: AMH is specifically measured to evaluate ovarian reserve as it reflects the remaining egg supply. LH and FSH are involved in the menstrual cycle but are not direct indicators of ovarian reserve. Progesterone indicates ovulation but not egg quantity.

3. Sperm Survival in Female Tract

   How long can sperm typically survive inside the female reproductive tract?

   1. Exactly 1 day
   2. About 12 hours
   3. Less than 1 hour
   4. Up to 5 days

   Explanation: Sperm can remain viable for up to 5 days in optimal conditions, giving a fertile window around ovulation. Less than 1 hour, 12 hours, and exactly 1 day underestimate sperm longevity and do not account for the observed survival range.

4. Menstrual Cycle Fertility

   Which phase of the menstrual cycle is considered most fertile?

   1. The ovulation phase
   2. The follicular phase
   3. Menstruation
   4. The luteal phase

   Explanation: The ovulation phase marks the release of an egg and is when conception is most likely. The follicular phase leads up to ovulation but is slightly less fertile. The luteal phase follows ovulation, while menstruation is generally not fertile.

5. Lifestyle and Fertility

   Which lifestyle factor is known to reduce fertility in both men and women?

   1. Drinking water
   2. Smoking
   3. Moderate exercise
   4. Eating vegetables

   Explanation: Smoking is linked with reduced fertility due to its negative effects on egg and sperm quality. Drinking water, eating vegetables, and moderate exercise generally support overall reproductive health.

6. Key Vitamin for Early Pregnancy

   Which vitamin is especially important before and during early pregnancy?

   1. Vitamin D
   2. Folic acid
   3. Vitamin B12
   4. Vitamin C

   Explanation: Folic acid helps prevent neural tube defects, making it critical during early pregnancy. Vitamin C and D support general health but are less specific for fetal development. Vitamin B12 is important but not uniquely crucial in early pregnancy like folic acid.

7. Menstrual Cycle Average Length

   What is the average length of a normal menstrual cycle?

   1. About 7 days
   2. About 14 days
   3. About 35 days
   4. About 28 days

   Explanation: A typical menstrual cycle lasts around 28 days, though it can vary. Fourteen and seven days are too short, while thirty-five days is longer than average but still within the normal range for some people.

8. Common Cause of Female Infertility

   Which condition is a common cause of infertility in women and involves irregular ovulation?

   1. Polycystic Ovary Syndrome (PCOS)
   2. Endometriosis
   3. Thyroid disorder
   4. Amenorrhea

   Explanation: PCOS often causes irregular ovulation and is a leading cause of female infertility. Endometriosis affects fertility too, but mainly due to tissue growth, not ovulation. Amenorrhea is absent menstruation, and thyroid disorders can impact cycles but less directly.

9. Home Ovulation Testing

   What test is commonly used to confirm ovulation at home?

   1. Pregnancy test
   2. Pap smear
   3. Blood sugar test
   4. Ovulation predictor kit (LH test)

   Explanation: An ovulation predictor kit (which detects the LH surge) can confirm ovulation at home. Pregnancy tests confirm conception, not ovulation; Pap smears check cervical health; blood sugar tests do not relate to ovulation.

10. Fertility Evaluation Timeline

    After how many months of trying to conceive should a couple consider fertility evaluation if the woman is under 35 years old?

    1. After 3 months
    2. After 24 months
    3. After 12 months
    4. After 1 month

    Explanation: Couples under 35 are typically advised to seek evaluation after 12 months of trying without success. One or three months is too soon, while 24 months might delay helpful intervention.
